Thomas Seigler discovered the springs, and a resort grew up by the 1870s. In 1909 there was accommodation for about 150 guests in four or five cottages and a frame hotel with a large stone dining room. As well as the tub and plunge baths of mineral water, the creek had been dammed to make a swimming pool. Stone for the main dining room and part of the hotel had been quarried from a nearby body of light-colored volcanic tuff. As of 1914 the resort was owned by the Seigler Springs Company, with chairman A.J. McGill and manager W.H. Roberts. The hotel was supplied with farm and dairy products from the ranch maintained as a part of the resort, comprising a total of . There were accommodations for 230 people. No water had been bottled for sale, but they were considering doing so. The Big Sulphur spring was the main one supplying the swimming pool, which was and deep. The pool had been made by damming the small ravine at the upper end of which several springs issue. Besides this, several of the other springs had stone bathhouses built over them, large enough for swimming. The Seigler post office opened in 1904, closed in 1907, reopened in 1909, and closed for good in 1911. It was replaced by the Seigler Springs post office, which operated from 1915 to 1969. In 1934 the Hoberg brothers, Captain Olsen and his son Ernie Olsen bought Seigler Springs Resort. They restored and modernized the resort, and it became so popular it could not provide room for all the would-be visitors. One cabin was named
S.S. Acme in honor of Captain Gudmund Olsen. In 1943–1944 the Hoberg Brothers bought most of Seigler Valley. A runway was built in Seigler Valley in 1946. The
Paul Hoberg Airport opened in 1947, half a mile from Seigler Springs, to serve
Hoberg's Resort. At this time the resort had a coffee shop and dining rooms. There were mineral baths, a heated indoor mineral plunge and an outdoor freshwater pool. Activities included dancing, hiking, badminton, ping pong, tennis and shuffleboard. There were riding stables and golf courses nearby. The Hoberg brothers sold their interest in Seigler Spring to the Olsens in 1948. As of 1953 Captain Olsen still owned and operated the resort with his son and family. They ran it as a family resort, and did not particularly encourage custom from the fliers from the nearby airport. Later Dorothy and Ernest Olsen took over and were more welcoming. In 1965 Paul Pieri and Bill Hecomovich, who had married the two daughters of Dorothy and Ernest, were managers and actively encouraged business from the pilots. The Seigler Springs Subdivision was created from part of the resort property in 1966, with 52 lots. The property was purchased for the Integral Yoga Institute and Swami Satchidananda in 1972, and it was called Yogaville West. It was a fairly strict community. Numerous single women were having discomforting experiences, and one day, in the kitchen, compared notes. They all had a similar feeling of someone sitting on their chest in the middle of the night. Satchidananda said it was a ghost, left over from the more "swinging" days, and that we should keep our rooms clean and burn lots of incense. In 1974 the resort became the main Ruchira Sannyasin Sanctuary in the United States, where
Adi Da taught until the early 1980s. The Seigler Springs resort as of 1989 was still being used as a private retreat. It contained historic buildings representative of early Twentieth Century resort-styled architecture. As of 2015 there were single family homes on 48 of the lots in the Seigler Springs Subdivision, mostly owned by Adidam devotees. The
Valley Fire of 12 September 2015 destroyed 38 of the homes. ==Notes==
